Multistage Centrifugal Pump Overview

Rotodynamic pumps that make use of a rotating impeller to increase the velocity of a fluid are known as a centrifugal pump. Centrifugal pumps that feature two or more impellers are known as a multistage centrifugal pump. Different impellers may be mounted on a common shaft or they may be mounted on different shafts.

Multistage centrifugal pumps have two basic functions to perform. The first function is producing a high lead. The second function is to discharge the liquid in large quantities. For developing a high head impellers are installed on the same shaft. Impellers are placed on different shafts only when the liquid is supposed to be discharged in large quantity.

The multistage pump is a more economical way of creating high pressure with a single pump. Developing a centrifugal pump that possesses a differential pressure of 150psid or more is quite expensive to design and maintain. In a multistage pump, the internal channels in the pump casing divert the discharge of one impeller to the suction of another impeller.

Like everything else there are some basic features of multistage centrifugal pumps too. the first and the most prominent feature is a multi-stage design. All thanks to the design, the user of the pump can avail a quiet, steady and a vibration-free it is the design of the pump that helps in delivering a trouble free experience to the user. The impeller is the most important part of the centrifugal pump. These impellers feature a thermoplastic precision molded and is 20% glass filled for a high level of efficiency. A very compact design is another notable aspect of these pumps. These pumps are close coupled and thus save a lot of space while installation. Unlike other pumps, the centrifugal pump does not require a flexible coupling and bedplate. The multistage pump allows mounting in two directions - vertical or horizontal. These pumps feature a stainless steel pump that have a hex design. This hex design enables a positive drive for the impellers and weeds out the need for clearance adjustments. If you are using the multistage pump, the last thing that you need to worry of is it being corroded by external or internal factors. The pump is covered with an electronic paint both on the inside and the outside and then baked o for enhanced resistance. You would even notice some O-rings throughout the pump. These rings are me4ant for positive sealing. Servicing this pump is not at all difficult. All you need to do is just remove four bolts. It is these features of the multistage centrifugal pump that makes it idea for various purposes. If you seek to know any more about the pump, you can refer to various websites.
